Fiber is somewhat hard to find, may take some looking. The holes have to be brushed out to get the old RTV chunks and locktite out of them. Tightening a bolt into a hole with enough junk in it can break the block. Head bolt hole cleanliness is critical for proper torque.
I don’t know if this a regional thing, but yesterday I phoned two area gun shops to ask if they carry the brushes. The neither shop stocked them. The second shop told me they don’t stock them because none of their customers want or buy them. The guy I spoke to said he was a x-machine shop mechanic and they used to get their brushes from a particular race-shop auto store. I went there, they had them, and they are made of stiff stubby nylon. Three different sizes per pack.

-Fill a squirt pistol type oiler with the same oil.

What does one of these squirt pistols look like and is there a special place to find them? Are these plastic squirt pistols for kids? Seems it would be pretty messy filling them up with oil.
